NI (Nasdaq: NATI), the provider of a software-defined platform that helps accelerate the development and performance of automated test and automated measurement systems, has announced a real-time sub THz software defined radio (SDR) for 6G research built on NI´s mmWave Transceiver System (MTS) and Virginia Diodes´ (VDI) radio heads, the company said.
Using VDI radio heads, the frequency range of the MTS can extend into the sub THz range. Because this testbed is built using SDRs and FPGAs, the software can be upgraded and customized to meet a wide range of research needs and applications. Users can leverage existing software reference designs for channel sounding or wireless communications protocols to create a real-time testbed for 6G research.
The development cycle of a typical wireless standard is approximately 10 years. As the commercial rollout of 5G begins in 2019, wireless communications researchers are already investigating the technology and ideas that will serve as the foundation of 6G. The use of sub THz and THz frequencies has numerous applications for communications and is likely to be a major area of 6G research in the foreseeable future.
The NI and VDI sub THz testbed provides up to 2 GHz instantaneous bandwidth and frequency ranges between 110–170 GHz.
